[i2c] Microchip PIC i2c

[Petr Jakeš]

Hi,
I am using following configuration:

HW: 
AMD Geode GX CPU + AMD Geode CS5536 Companion Device
SMSC SCH3114 super I/O chip

SW:
Ubuntu 7.04 (minimalistic command line distro)
kernel 2.6.20-15-386
sensors version 2.10.4-SVN with libsensors version 2.10.4-SVN
drivers: scx200_acb, i2c-dev, compiled dme1737
py-smbus

I would like to know, if is possible to set lm-sensors to communicate "pure" i2c, not a SMBus protocol. We are trying to connect a Microchip PIC 16F88 which has HW i2c port. 
We can see this chip on the bus, we can communicate with it (using py-smbus) but sometimes i2c port on the PIC freezes. We suspect the slight diferences between i2c and SMBus protocol causes this. 

BTW I do not realy understand which way are informations in /sys/class/hwmon/hwmon0/device acquired? Via SMBus or via ISA bus?
sensors-detect returns:
Use of uninitialized value in pack at /usr/sbin/sensors-detect line 2197.
Success! (address 0x3f0, driver `dme1737')

Thanks for your comments.
